The C++0x standard draft defines a trivial type as one that has trivial default
construct, copy constructor, copy assignment operator and destructor. g++ from
the current trunk, however, classifies types without default constructor as
trivial, meaning that the following code does not compile:
#include <type_traits>
struct Foo {
Foo(int) {}
};
static_assert(!std::is_trivial<Foo>::value,
"Not trivial - no (trivial) default constructor.");
This seems like a bug (unless I've misunderstood the draft or missed some
pending change to it).

------- Comment #1 from paolo dot carlini at oracle dot com 2009-09-20 19:11 -------
Jason, can you have a look to this issue? I believe submitter is right. Should
we use TYPE_HAS_TRIVIAL_DFLT instead? Note sure about
TYPE_HAS_TRIVIAL_INIT_REF, TYPE_HAS_TRIVIAL_ASSIGN_REF, and
TYPE_HAS_TRIVIAL_DESTRUCTOR. Humm, maybe just "reversing" the logic in
trivial_type_p is enough?!?
